Obesity is a multifactorial disease defined by a pathological accumulation of body fat. Its prevalence has increased greatly across the world. Chile has one of the highest prevalence of obesity among OCDE countries. It is caused by a sustained difference between energy expenditure and intake, keeping a positive delta, which drives fat accumulation. However, its etiology is comprised several factors: psychological, genetics, environmental, etc. The environment plays a key role in the predisposition towards food consumption, the adoption of exercise, and genetic susceptibility, increasing or decreasing the genetic load towards obesity. This modification of susceptibility is known as epigenetics, which refers to modifications over genetics, which are highly modifiable by environmental factors. Some of these modifications can be inherited from one generation to another, granting a higher complexity level regarding designing novel complementary therapies against obesity. Thus, the present review described which epigenetic modifications are related to obesity and different dietary patterns, and finally how epigenetic modifications can be related to transgenerational transmission of obesity.
